How many crystal system are there when $\mathrm{a}\ne \mathrm{b}\ne \mathrm{c}$ and $\mathrm{a}=\mathrm{b}=\mathrm{c}$?

The lattice point per unit cell in the figure

is

A match box exhibits

The cubic unit cell of a metal (molar mass $=63.55 \mathrm{g}{ \mathrm{mol}}^{-1}$ ) has an edge length of $362\mathrm{pm}$. Its density is $8.92{\mathrm{gcm}}^{-3}$. The type of unit cell is

The radius of sodium atom isfs $1.857\times {10}^{-8} \mathrm{cm}$. If sodium crystal is a body centred, then the edge length of unit cell is

Number of unit cells present in a cubic shaped ideal crystal of $\mathrm{NaCl}$ of mass $1.00 \mathrm{g}$ is [Molecular mass $=58.5$]

Pink colour of non-stoichiometric $\mathrm{LiCl}$ is due to
